use the blitter + custom stage to avoid doing a whole lot of state
setup by hand. This makes life a lot easier for doing this on evergreen
it also keeps all the state setup in one place.
We setup a custom context state at the start with a flag to denote
its for the flush, when it gets generated we generate the correct state
for the flush and no longer have to do it all by hand.
this should also make adding texture *to* depth easier.

at least zreaddraw works for me here now on my rv610

once I go past 0x3f80000, I can't translate hex to float in-brain anymore.

When calling query begin using same query id we need to discard
previous query results.

Shader rebuild should be more clever, we should store along each
shader all the value that change shader program rather than using
flags in context (ie change sequence like : change vs buffer, draw,
change vs buffer, switch shader will trigger useless shader rebuild).

nothing was every dirtying the object again, the mesa-demos
reflect test was just stalling.
this fixes glean readPixSanity.

need to write two components to get stencil components as well
|
|
add cb/db flush states to the blit code.
add support for the rv6xx that need special treatment.
according to R6xx_7xx_3D.pdf
set r700 CB_SHADER_CONTROL reg in blit code
docs say dual export should be disabled for DB->CB

texture border regs are indexed on evergreen.

eg seems to have a higher pitch aligmment requirement and uses r700 cube setup
this fixes a couple of piglit tests here.
|
|
running piglit's texrect-many caused the vtx to overflow.

This allow to share code path btw old & new, also
remove check on reference this might make things
a little slower but new design doesn't use reference
stuff.

If we are not going to write to the X or Y components of the destination
vector we also don't need to prepare to compute SIN or COS.

So texture code can be shared btw new state design
& old one.

I didn't do r600d according to the docs; I split EXPORT_MODE to be a bit more
useful and obvious. Hope this is okay.

r600c emits this with a mask of each written output.

this fixes fbo-cubemap on r700.

we were leaking buffers since the flush code was added, it wasn't dropping references.
move setting up flush to the set_framebuffer_state.
clean up the flush state object.
make more space in the BOs array for flushing.
|
|
this just uses the common code from r300g now in util to do translations on r600g.

This reverts commit a1d9a58b825825723f1c5f7705f2ed3ef834038a.
Flushing the upload buffers on draw is wrong, uploads aren't supposed to
cause flushes in the first place. The real issue was
radeon_bo_pb_map_internal() not respecting PB_USAGE_UNSYNCHRONIZED.
|
|
Unless e.g. PB_USAGE_DONTBLOCK or PB_USAGE_UNSYNCHRONIZED would be specified.
|
|
radeon_ws_bo_map() will already take care of that if needed.
|
|
If a upload buffer is used by a previous draw that's still in the CS,
accessing it would need a context flush. However, doing a context flush when
mapping the upload buffer would then flush/destroy the same buffer we're trying
to map there. Flushing the upload buffers before a draw avoids both the CS
flush and the upload buffer going away while it's being used. Note that
u_upload_data() could e.g. use a pool of buffers instead of allocating new
ones all the time if that turns out to be a significant issue.

On r6xx if an MOVA instruction is emitted we should set this bit.
|
|
This makes the 'glsl1-gl_FrontFacing var (1)' piglit test pass.

The variables are used in code that is currently ifdef'ed out.

Winsys context build a list of register block a register block is
a set of consecutive register that will be emited together in the
same pm4 packet (the various r600_block* are there to provide basic
grouping that try to take advantage of states that are linked together)
Some consecutive register are emited each in a different block,
for instance the various cb[0-7]_base. At winsys context creation,
the list of block is created & an index into the list of block. So
to find into which block a register is in you simply use the register
offset and lookup the block index. Block are grouped together into
group which are the various pkt3 group of config, context, resource,
Pipe state build a list of register each state want to modify,
beside register value it also give a register mask so only subpart
of a register can be updated by a given pipe state (the oring is
in the winsys) There is no prebuild register list or define for
each pipe state. Once pipe state are built they are bound to
the winsys context.
Each of this functions will go through the list of register and
will find into which block each reg falls and will update the
value of the block with proper masking (vs/ps resource/constant
are specialized variant with somewhat limited capabilities).
Each block modified by r600_context_pipe_state_set* is marked as
dirty and we update a count of dwords needed to emit all dirty
state so far.
r600_context_pipe_state_set* should be call only when pipe context
change some of the state (thus when pipe bind state or set state)
Then to draw primitive you make a call to r600_context_draw
void r600_context_draw(struct r600_context *ctx, struct r600_draw *draw)
It will check if there is enough dwords in current cs buffer and
if not will flush. Once there is enough room it will copy packet
from dirty block and then add the draw packet3 to initiate the draw.
The flush will send the current cs, reset the count of dwords to
0 and remark all states that are enabled as dirty and recompute
the number of dwords needed to send the current context.
